타원형의 파이프(2)에 길이방향으로 돌편(3)을 형성하여서 된 열교환관(1)에 있어서 타원형파이프(2)의 하부에는 여러개의 톱니형돌기(4)를 형성하여 분사되는 냉각수를 신속히 낙하 시킬 수 있도록 한 것인데, 제조에따라서는 타원형의 파이프(2)를 원형의 파이프(2')로 제조할 수도 있으며 양측에 톱니형돌기(4)를 형성할 수도 있다.In the heat exchanger tube 1 formed by forming the stone pieces 3 in the longitudinal direction in the elliptical pipe 2, a plurality of toothed protrusions 4 are formed in the lower part of the elliptical pipe 2 to rapidly drop the cooling water injected. It is intended to be, depending on the manufacture may be made of oval pipe (2) as a circular pipe (2 ') and may form a toothed projection (4) on both sides.

이와 같은 본 고안은 공조기나 냉동기의 응축기등의 열교환기(6)의 내에 도3과 같이 배관하여 물받이통(7)의 냉각수를 펌프(9)및 공급관(10)에 의하여 냉각수분사관(8)으로 공급하여 노즐(801)로 분사시키과 동시에 송풍팬(11)에 의하여 공기를 상부로 이동시켜 열교환이 이루어지게 하여 열교환관(1)를 흐르는 냉매등의 열매체를 냉각 및 증축시키게 되는 것은 공지와 동일한 바, 상기의 작동에 있어서본원의 열교환관(1)에는 일정한 간격으로 여러개의 톱니형돌기를 형성하였으므로 노즐(801)에서 분사된 냉각수가 열교환관의 표면을 타고 하방으로 흐를때에 냉각수는 도1과 같이 톱니형돌기(4)의 끝으로 신속히 이동되어 낙하된다.In this invention, the cooling water spray pipe 8 is pumped by the pump 9 and the supply pipe 10 to the cooling water of the water receiving tank 7 by piping as shown in FIG. 3 in a heat exchanger 6 such as an air conditioner or a condenser of a refrigerator. It is supplied to the nozzle 801 and sprayed to the nozzle 801 and at the same time by moving the air to the upper by the blower fan 11 to perform heat exchange to cool and expand the heat medium such as the refrigerant flowing through the heat exchange tube (1) In the above operation, since a plurality of tooth-shaped projections are formed in the heat exchange tube 1 of the present invention at regular intervals, when the cooling water injected from the nozzle 801 flows downward through the surface of the heat exchange tube, the cooling water is shown in FIG. As shown in the drawing, it is quickly moved to the end of the toothed projection 4 and falls.

이에 따라 물막(5)의 뚜께는 매우 얇게 되어 송풍팬(11)의 흡입력에 의한 하부에서 상부로 이동되는 공기에 의하여 열교환관(1)의 방열작용이 매우 양호하게 이루어지게 됨과 아울러 상부의 열교환관(1)에서 하부의 열교환관(1)으로 떨어지는 물방울(5')은 톱니형돌기(4)에 의하여 도1과 같이 균일한 간격으로 떨어져 골고루 분포되게 됨으로 열교환관(1)내의 냉매의 냉각효율은 향상되는 것이다.Accordingly, the thickness of the water film 5 becomes very thin, so that the heat dissipation of the heat exchanger tube 1 is performed very well by the air moving from the lower part to the upper part by the suction force of the blower fan 11, and the heat exchanger tube of the upper part Water droplets 5 'falling from the lower heat exchange tube 1 in (1) are evenly distributed evenly at intervals as shown in FIG. 1 by the toothed projections 4, thereby cooling efficiency of the refrigerant in the heat exchange tube 1 Is to be improved.

이와 같은 본 고안은 열교환관(1)에는 여러개의 톱니형돌기(4)를 형성하여 냉각수를 신속히 낙하되도록 하였으므로 물막(5)이 얇게 됨과 아울러 상부 열교환관(1)에서 하부의 열교환관(1)에 일정한 간격으로 물방울(5')이 떨어져 골고루 분포케 됨으로 열교환 효율을 향상시킬 수 있는 효과가 있다The present invention is formed in the heat exchange tube (1) to form a plurality of jagged projections (4) so that the coolant drops quickly, so that the water film (5) is thin and the heat exchange tube (1) of the lower part in the upper heat exchange tube (1) The water droplets (5 ') are evenly distributed at regular intervals, thereby improving heat exchange efficiency.
